Embodiment
Fig. 1 is the flow chart that is used for orthogonal sequence is assigned to the method for user equipment (ue) device UE that illustrates according to an embodiment.UE forms the group of the channel (the for example automatic repetitive requests indicator channel of physical mixed PHICH) of sharing telecommunication system.Confirm in the step 100 at UE, confirm that which UE of group has the maximum transmission resource of appointment.Maximum transmission resource of assigning can be regarded as having the highest appointment power UE or have the UE of the Resource Block of maximum appointments.Transmit resource and also can be based on the overall judgement of Resource Block amount of power and the appointment of appointment.The transmission resource of assigning can be the transmission resource of assigning for physical uplink link sharing channel PUSCH.
Confirm in the step 102 that in sequence the maximum that has appointment in confirming to organize transmits first orthogonal sequence of the UE of resource.Here, " confirming " can be for example in the communication of normal (up) and operation, to search the orthogonal sequence of having assigned, or assigned orthogonal sequence when setting up communication for example.
Confirm in the step 104 at orthogonal sequence, confirm to equal second sequence of the quadrature phase offset of first orthogonal sequence.That is to say that if first sequence for example is "+1 ,-1 ,+1 ,-1 ", then second sequence is "+j ,-j ,+j ,-j " (with complex representation).When the phase error of first sequence occurring, its orthogonal attributes to second sequence will be demoted.In theory, if phase error reaches 90 degree, then first sequence will become and equal second sequence, and their certain no longer quadratures.Yet also with producing and the relevant interference source of any communication that uses second sequence, this can produce very important performance degradation to little phase error.
In sequence keeps step 106, kept second sequence, make in assigned sequence during to the residue UE that organizes, as long as there is other orthogonal sequence to use, just avoid this second sequence.Therefore, the effect of aforesaid any phase error is able to avoid, or at least only is exposed to the UE with the transmission resource of still less assigning.
Optional is that this process circulates, and makes that similarly process repeats the residue UE of group shown in optional remaining set definition step 108.Therefore, from remaining group, the maximum of confirming to have appointment transmits the UE and the orthogonal sequence thereof of resource.Orthogonal sequence based on confirming keeps another sequence.Subsequently, can also carry out the another circulation of remaining set, and by that analogy.In fact, through will transmitting resource consumption body (consumer) classification, the similar effect that can realize and circulate, and can carry out confirming/the assigned orthogonal sequence based on same principle.For the situation that similar all available orthogonal sequences must be used, this can advantageous particularly.
Fig. 2 is the state diagram of redistributing and operating that illustrates according to the orthogonal sequence state of an embodiment.The UE of consideration group has according to reference to its sequence that any embodiment assigned shown in Figure 1, that is, carried out state-transition according to arrow left, and operated through carrying out its transmission.Therefore, the state of group is in the mode of operation shown in left side state bubble.Yet, shown in the bubble of arrow and right side state to the right, be used for confirming redistributing the mechanism that whether can improve performance and can starting to the transformation that sequence is redistributed state of orthogonal sequence.The criterion that changes can be to detect the change that transmits the UE of resource consumption body as maximum.This can be that the situation of changing (be new UE adding group, perhaps one or more UE have left group) has been changed or organized to the transmission condition.Criterion can also be the certain hour of process.In redistributing state, group is according to coming implementation with reference to any embodiment shown in Figure 1.
Be fit to by means of realization according to the method for the invention such as processing unit such as computer and/or processors.Therefore, will a kind of computer program that comprises instruction be provided with reference in the described any equipment of Fig. 4 below, said instruction is arranged to impel processing unit, processor or computer to carry out according to the step with reference to the method for the said any embodiment of Fig. 1.Computer program preferably includes stored program code on the computer-readable media as shown in Figure 3 300, and this program code can and be carried out to impel it correspondingly to carry out as according to the method with reference to the described any embodiment of Fig. 1 by processing unit, processor or computer 302 loadings.The computer 302 and the computer program 300 that preferably can in network node as shown in Figure 4, exist can be arranged to executive program code in order; Wherein, The action of any method is progressively carried out or is being carried out on the basis in real time, wherein according to the availability of the input data that need with need take action.Processing unit, processor or computer 302 preferably are called embedded system usually.Therefore, it is only to be used for illustration purpose that computer-readable media shown in Fig. 3 300 should be regarded as with computer 302, so that the understanding of principle to be provided, and should not be regarded as any direct diagram of key element.
For the demonstration telecommunication system, the appointment of orthogonal sequence is based upon and transmits the begin block of assigning.Therefore, the appointment of orthogonal sequence is directly related with the selection of begin block.Begin block can define through frequency indices again.This type of demonstration telecommunication system can be for example third generation partner program Long Term Evolution (3GPP LTE) etc. based on the system of OFDM.
Fig. 4 schematically illustrates according to the block diagram of the control circuit 400 of an embodiment and mutual with the demonstration of communication network part thereof.Control circuit 400 is arranged at orthogonal sequence to control nodes of telecommunication network 402 aspect the distribution of the user equipment (ue) device UE 404 of the group of sharing transfer channel.Physically, control circuit 400 can provide in nodes of telecommunication network 402, and the Long-distance Control of node 402 perhaps for example is provided from the network node controller that can be arranged to control one or more network nodes.
Therefore; The UE that the maximum that sequence moderator 408 can be arranged to from group, to have appointment transmits resource begins; The order assignment orthogonal sequence of pressing the transmission resource of assigning is to UE; And the tabulation with each orthogonal sequence classification is provided according to the transmission resource of the appointment of any UE of the sequence with distribution (this sequence has phase deviation, is the orthogonal sequence that is used for UE).Can come classification according to the transmission resource of the appointment of corresponding UE as a plurality of orthogonal sequences of the orthogonal sequence that has phase deviation of any UE that is assigned to group, make that the orthogonal sequence classification must be high more, but keep longly more in the lower hierarchical sequence time spent.
Based on control, send the appointment of the orthogonal sequence of the transmission that is used for UE 404 to UE from network node 402 through signal.
